Requires a LEGO WeDo and some monkeys! (Well, you can just have your friends pretend to be monkeys if you dont have any monkeys around). Build the LEGO WeDo monkey, pictured here: http://www.flickr.com/photos/curiouslee/2702464699/ Put the distance sensor in the monkey's face as if it were his nose. Plug in your WeDo and open this project in Scratch. When you hold something up to the monkey's nose, he won't like it and will get mad... (unless you press space bar first, in which case he will like the smell!) This is a fun story project we used in a recent workshop with WeDo. Credit to Elijah for the idea and sprites.
